GitMensch commented 3 years ago

Describe the bug The old one works, the new one pops up shortly then exits with a return code of 1.

To Reproduce on this specific RHEL7 here Older one works, the newer one not.

The X11 connection broke (error 1). Did the X11 server die?

Note: after the message "Did the X11 server die?" I can start the older one, so the answer to that question is "no".

Nasty, can you try to run the appimage with --appimage-extract, then edit the AppRun script to start the bundled application in gdb and see if you can get a backtrace to where it crashes?

GitMensch commented 3 years ago

Looks like I made it but actually there is no "chrash" directly, the application just exits with code 1. Not sure if this debug session helps...

I guess that would be this one here:

    int connection_error = xcb_connection_has_error(xcb_connection());
    if (connection_error) {
        qWarning("The X11 connection broke (error %d). Did the X11 server die?", connection_error);
        exit(1);
    }

oh boy I wonder how to resolve that then ;-)

GitMensch commented 3 years ago

Hm,, the question would be: what has changed since hotspot-v1.3.0-x86_64-NoRustDemanglingForCentOS7.AppImage?

the code in question
packaging of the appimage

I guess one of those must be true and may be tweaked.

milianw commented 3 years ago

the previous appimage was compiled on an older ubuntu that is now EOL. the new appimage is build using centos7 which is a completely new setup and thus a different set of libs get merged. one would have to find the time to investigate and debug that, I don't have the time for that right now (esp. considering that the appimage seems to work on other distros).

GitMensch commented 3 years ago

Tested on a different RHEL7:

worked out of the box:

hotspot-v1.3.0-x86_64-NoRustDemanglingForCentOS7.AppImage

had the same issues:

hotspot-v1.3.0-77-gdf39e78-x86_64.AppImage
hotspot-v1.3.0-79-gd06e376-x86_64.AppImage

issues:

clean error message: missing FUSE (fuse3 was installed, but not fuse) -> copied over libfuse.so.2 from CentOS7
symbol lookup error: /tmp/.mount_hotspo$randomid//usr/lib/libQt5XcbQpa.so.5: undefined symbol: FT_Get_Font_Format -> fixed by also copying the matching libfreetype from CentOS7 and placed that in LD_PRELOAD
either does not start or exits on resize with the "The X11 connection broke (error 1). Did the X11 server die?" message

As the last issue (which also was the initial one) is solved by replacing XMing (old Public Domain version) by VcXsrv (also removing the warning messages "X server does not support XInput 2" and "failed to get the current screen resources") I declare that this isn't an RHEL7 or Hotspot issue but an issue with the X-Server. Thanks for all the help.
